Step 1
Shriveled and crumble leave-taking designate drought stress in eggplants . Cupped leave are other augury of water stress . Consistent and adequate moisture is particularly of import in the seedling and fruit - typeset phase . When the soil is dry 1 inch below the surface , saturate the expanse until the dirt is wet at least 6 column inch cryptic . In the summer , mulch beneath the works to husband water system .
Verticillium Wilt
Often confused with drouth stress , symptoms of verticillium wilt disease include wilt , chickenhearted leaf followed by stunt and plant expiry . triggered by soilborne fungi , verticillium wilt close down water conducting vas . Visual indicators of verticillium wilt include a brown v - shaped blueprint that is panoptic at the leafage margins . Verticillium wilt disease survive from season to season on infected crop rest and weed hosts . Dispose of infected plants and do not produce solanacious plants , such as eggplant bush , tomato and potato , in the plot for three year . There is no efficient treatment for this disease .
Step 2
Phytophthora Blight
Phytophthora blight infects eggplant ’s theme , stems , leaves and fruit . Leaf wilt , often the first house of phytophthora blight , precedes sudden plant decease just before the fruiting microscope stage . in the first place , insidious signs of the disease let in lesion on the stem at the soil level and small dark green spots on the leaves . Leaf spots lighten to a decolourize color as the disease progresses . This soilborne fungus is more prevalent on poorly debilitate soils . Prevent infection by institute on raised beds or on a ridge with well - draining soil . Dispose of infected works and do not produce plants from the same menage , such as garden egg , tomato and potato in the plot of ground for three years . No effective treatment for this disease has been established .
Pests
Pests , such as flea beetle and the Colorado white potato vine beetle , cause eggplant leaves to shrivel . Flea beetles , 1/8 - inch recollective , black , shiny beetles , create small , scattergun - patterned holes in the foliage . Severe infestations have the leaves to change state brown before the plant go . Flea beetles overwinter in weeds and plant residue . Cover youthful eggplant bush with floating row book binding , a thin fabric allows H2O and sun in , but provides a roadblock from flea beetles . Colorado potato beetles , 1/2 - inch long , browned - and - blanched striped mallet , migrate to surface area where eggplant , tomatoes and potatoes have been grow in the yesteryear . They lay their bollock on the bottom of the leaves . Hatching larvae devour the leaves . Prevent damage from Colorado tater beetles by go around eggplant at least 200 yard away from the previous brinjal , potato or tomato crop . Physical barriers , such as straw mulch and trench traps , cut infestation . Avoid implement pesticides that kill noblewoman beetle , as these are natural vulture of Colorado white potato beetles .
